RAZOR-GAG E.

I SPECIFICATION forming' of Letters Patent No. 692,576, dated February 4, 1902.

Application filed October 8, 1901. Serial No. 77,969. (No model.)

To all whom it may concern,.-

Be it known that I, AL'ExIs WITTE, a citizen of the United States, residing in New York, borough of Brooklyn, and State of New York, have invented certain new and useful Improvements in Razor-Gages, of which the following is a specification.

This invention relates to an improved razorgage which is intended to be used by barbers and others who use a large number of razors as a practical means to test almost instantly whether the thickness of the backs of razors compare to the width, conform to a certain standard, and to readily determine the coneavity of the blade; and for this purpose the invention consists of a razor-gage composed 0f a dat plate provided with a wedge-shaped opening and with a plurality of convex arcs formed at the sides and ends of the plate, said arcs determining the diderent concavities to which the razors are ground, while the wedge-shaped opening serves for gaging the thickness of the back of the blade, as will be fully described hereinafter and :finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a front view of my improved razorgage; and Fig. 2 is a horizontal view of the same on line 2 2, Fig. l.

Similar letters of reference indicate correconvex arcs are of different degrees of curvature and are provided with marks denoting full, three-quarters, half, &c., concavity.

l My improved razor-gage is used as follows: To determine whether a razor is ground to the proper concavity, its concaved side is applied to one of the arcs on the gage until the are Atherazor is made according to normal requirements, and if thinner or thicker it can be easily seen thatthe same is not according to standard requirements.

My improved razor-gage forms thereby a useful fdevice for barbers and others who use a large number of razors for properly controlling the razors supplied to them and whether they areaccording to the requirements as to thickness of back and concavity. As the different arcs are marked so as to correspond to the standard thickness of back and concavity, the thickness of back and concavity of razors can be quickly determined,and thereby in purchasing razors the required standard of concavity and proper proportions of thickness of back to width controlled.

. Having thus described my invention, I claim as new and desire to secure by Letters Patentits edges with convex arcs each different in' curvature from the others, substantially as set forth.

2. A razor-ga, re,v consisting of a plate generally rectangular in outline, but provided at its edges with convex arcs each different in curvature from the others, and a uniformlytapering gage-opening in said plate, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
